This value should be lowered if visual acuity is worst then 20/20, raised if visual acuity is better. Closer to the screen than this may result in the need for higher resolution display. This distance represents the point beyond which some details in the picture are no longer able to be resolved, so pixels begin to blend together. Price calculator and screen aspect ratio yard Meter yards mm cm m km yd in mi Lngeneinheiten Inch Zoll Zentimeter Centimeter Foot Meter Kilometer, Miles. The human eye with 20/20 vision can detect or resolve details as small as 1/60th of a degree of arc. The Visual Acuity Distance based on Visual Acuity. This distance is calculated based on the reference resolving power of the eyes.(Note: sitting closer to the screen results in a wider field-of-view.) ⬆ THX recommends that the back row of seats in a theater have a 36 degree or greater viewing angle and requires a minimum of a 26 degree or greater viewing angle to receive certification. This is based on THX Longest Recommended and Longest Allowable viewing distances: THX publishes standards to which movie theaters must adhere to receive THX certification. You can calculate the screen ratio in three steps: Determine the width and height of the screen In this example, the width of the screen is 16 in. The audience should sit at most this far from the screen.This equates to a 70-degree field of view when the person is looking at the center of the screen. The rule is that if the viewer sits any closer than this distance to the screen and looks at one side of the screen, they will not be able to see the other side of the screen with their peripheral vision. TV Size Calculator for Shelf Space, Aspect Ratio, Dimensions Despite our desire for a home theater-style TV, physical limitations such as shelf or rack space often prevent us from enjoying a cinematic experience. The screen ratio for the screen in this example is 16:9. Determine the screen ratio of your screen Now, we can compare the screen ratio by comparing the number with the popular screen aspect ratio. Change any of the values at any time, or reset them to the starting values. Enter either a new width (W 2) or new height (H 2) on the right to calculate the remaining value. The average FOV width for the human eye is 140 degrees. Use this calculator to find the ideal size. The screen ratio formula is as follows: screen ratio width / height The screen ratio is the screen to design is 16 / 9. Enter the values for the original width (W 1) & original height (H 1) on the left. This is the Shortest Recommended Viewing Distance based on Field-of-View being too wide: This distance is calculated on the peripheral vision field of view of the human eye. The ratio will be displayed above the Example image below. You can work out what the aspect ratio of any given rectangle is by simply entering the physical dimensions into the W1 and H1 boxes. The audience should sit at least this distance from the screen. Viewing Distance Calculation Screen Size Resolution (W) Resolution (H) Update Data Display details: Screen Diagonal: inches Screen Resolution: Screen Width. The calculator will display the relative height in the H2 field.
